We have designed and synthesized a series of novel apocynin analogues, and evaluated their biological activity. Compound 10, an apocynin dimer analogue, compound 12, the lipoic acid (LA) and apocynin conjugate, were the most potent in protecting cells from lipopolysaccharide (LPS)-induced cytotoxicity, had significant activity scavenging ROS induced by LPS, and greatly decreased LPS-induced P67phox
我们已经设计和合成了一系列新颖的载脂蛋白类似物,并评估了它们的生物学活性。化合物10,一个夹竹桃麻素二聚体类似物,化合物12,硫辛酸(LA)和夹竹桃麻素缀合物,是最有效的在保护细胞免于脂多糖(LPS)诱导的细胞毒性,已经显著活性清除ROS诱导LPS,并显着降低LPS诱导的P67 phox蛋白表达。SAR分析表明,载脂蛋白的修饰可以增加其活性。我们的结果表明,用强大的抗氧化剂(如硫辛酸)武装载脂蛋白是设计新的具有增强生物活性的载脂蛋白类似物的有效策略。
